A continuous time model of European growth,integration and technology diffusion: The role of distance

Economists have been devoting increasing attention to the diffusion process of knowledge in economic activities. However, the models till now developed concentrate mostly on the dynamics determined by the steady state, when dealing with the interaction among many countries. Instead, we present a non-linear model where explicitly formalize the disequilibrium as starting point. We evaluate theoretically and empirically, with a continuous time analysis applied to panel data, the integration process of some main European countries by considering a simultaneous interaction among output, technology and business services. In this process we take particular care of distance, as a strategic variable over time, and of the following consequences on the convergence to the steady state. On this subject we also show a closed form solution in presence of a linear constraint on technology among countries.     

The stock market reaction to the 2005 split share structure reform in China

During 2005–2006, the Chinese government implemented the split share structure reform, aimed at eliminating non-tradable shares (NTS), i.e. the shares typically held by the State or by politically connected institutional investors that were issued at the early stage of financial market development. Our analysis, based on the time series of risk factors and on the cross-section of abnormal returns, confirms that the split share structure reform was particularly beneficial for small stocks, stocks characterized by historically poor returns, stocks issued by companies with low transparency and weak governance, and for less liquid stocks. Historically neglected stocks also witnessed an increase in the volume of trading and market prices. We conclude that the reform laid down the conditions for important future changes in ownership, liquidity and corporate governance in China.     

Growth Options, Beta, and the Cost of Capital

We show how to decompose a firm's beta into its beta of assets-in-place and its beta of growth opportunities. Our empirical results demonstrate that the beta of growth opportunities is greater than the beta of assets-in-place for virtually all industries over all periods of time dating back to 1977. The difference has important implications for determining the cost of capital. For example, when choosing comparables to determine a project beta one should match the growth opportunities of the project with those of the comparable firm. Assuming a 6% market equity risk premium, accounting for growth opportunities alters the project cost of capital by as much as 2% to 3%.     

Multidimensional scaling reliability in similarity judgments about environmental sentences

The aim of this research was to analyze the stability of Multidimensional Scaling (MDS). The investigations on this topic include studies related to the assumptions of linearity and monotonicity and to the validity and reliability of MDS procedures. Centered in this last topic, a test of the reliability of MDS procedure was carried out. We employed a set of complex stimuli: 21 sentences related to environmental field. 40 subjects made similarity judgements about both pairs “sentence A — sentence B” and “sentence B — sentence A”, so obtaining one square matrix per subject. Each of these matrices was broken down into two triangular matrices that were scaled separately by INDSCAL. The coordinates of stimuli in both MDS solutions were correlated. The results show a significant correlation between the two solutions.     

Competitive collaboration and market contestability: cases in Mexican and UK banking, 1945-75

In this article we explore the emergence and evolution of collaboration agreements among different types of intermediaries in the UK and Mexican financial systems. Collaboration in the UK looks at agreements between non-bank and non-finance providers aiming to modify their competitive capabilities and circumvent barriers to enter deposit markets. Collaboration in Mexican banking considered agreements between commercial banks and small regional banks during the period of 1945 to 1975. Agreements in Mexican banking are benchmarked against collaboration in the UK. As a result, research in this article sheds light on the success of collaboration agreements through changes in competitive strength rather than the longevity of the transaction or the formality and structural visibility of the agreements. Evidence documented here also helps in remedying a shortage of research around financial institutions in less developed countries and the economic and business history of Latin America, while providing an international comparison.     

Fluctuating Efforts and Interdependencies in Collaborative Work

We present a dynamical model of cooperative efforts comprised of concurrently performed, interrelated tasks. The model contains a stochastic component to account for temporal fluctuations both in task performance and in the effect of a given unit of work on the project as a whole. We show that as the number of concurrent tasks increases, so does the average completion time. Also, for fixed system size, the dynamics of individual project realizations can exhibit large deviations from the average when fluctuations increase past a certain threshold, causing long delays in completion times. These effects are in agreement with empirical observation. We also show that the negative effects of both large groups and long delays caused by fluctuations may be mitigated by arranging projects in a hierarchical or modular structure. Our model is applicable to any arrangement of interdependent tasks, providing an analytical prediction for the average completion time as well as a numerical threshold for the fluctuation strength beyond which long delays are likely. In conjunction with previous modeling techniques, it thus provides managers with a predictive tool to be used in the design of a project’s architecture.     

Why Do Governments Privatize Abroad?

Privatization through global equity market placement has largely contributed to financial market development and integration. Despite the relevance of the fact, the reasons underlying governments' choice to sell shares of privatized companies abroad are still poorly understood. This paper presents new evidence for a sample of 233 share issue privatizations in 20 OECD countries, showing that redistribution concerns and the objective of domestic financial market development make domestic privatization more likely. However, if budget constraints are binding, governments tend to sell abroad a larger quantity of shares, particularly when corporate governance at home is weak.     

The construction of qualitative research articles: a conversation with Eileen Fischer

Eileen Fischer, Professor of Marketing and Anne & Max Tanenbaum Chair in Entrepreneurship and Family Enterprise at the Schulich School of Business at York University, has published research on entrepreneurs, consumers, and markets in several leading management and marketing journals. Professor Fischer has served on the editorial review boards of Consumption Markets & Culture; Entrepreneurship: Theory and Practice; Family Business Review; Journal of Business Venturing; and Journal of Small Business Management and is a current co-editor of the Journal of Consumer Research. In preparation for this conversation, the interviewers invited questions about the construction of qualitative research articles from multiple junior scholars in the field of consumer culture theory (CCT). This invitation yielded dozens of questions that were whittled down to the final questions you see here.     

Dynamic coordination with timing frictions: Theory and applications

We present a general framework of dynamic coordination with timing frictions. A continuum of agents receive random chances to choose between two actions and remain locked in the selected action until their next opportunity to reoptimize. The instantaneous utility from each action depends on an exogenous fundamental that moves stochastically and on the mass of agents currently playing each action. Agents' decisions are strategic complements and history matters. We review some key theoretical results and show a general method to solve the social planner's problem. We then review applications of this framework to different economic problems: network externalities, statistical discrimination, and business cycles. The positive implications of these models are very similar, but the social planner's solution points to very different results for efficiency in each case. Last, we review extensions of the framework that allow for endogenous hazard rates and ex ante heterogeneous agents.
